Abstract (en)

The prosthesis has a stem, successive sections of which match the measured cross-section of the marrow chamber. It is inserted in the femur (10) in the anti-torsion plane, and its medial and lateral edges match the measured contour of the chamber (24). There can be ribs running along it on the ventral side, from the proximal end to halfway along,their height decreasing towards the distal end. The stem can be of rectangular cross-section, supported via its lengthwise edges from the femur compacta (26). The internal diameter fo the chamber can be determined by computer tomographs at intervals in the axial direction, and used to machine the stem from a flat blank plate.

Abstract (de)

Der Schaft (18) einer Hüfttotalendoprothese wird individuell dem computer-tomographisch ermittelten Querschnitt des Markhohlraumes des Femurs (10) angepaßt. Der Schaft (18) hat im Querschnitt die Form einer flachen Platte, die in der Antetorsions-Ebene in das Femur (10) eingesetzt wird. Die Anpassung erfolgt zweidimensional an dem medialen und dem lateralen Rand des Schaftes (18). <IMAGE>
